The 4th one because you can’t repeating x values with different y values.

I might be wrong but I’d say the second one [(1, 2), (3,-5), (-1, 7)]
I said that because the numbers in the parentheses are labeled (X,Y) and the -5 doesn’t go with 7. Meaning the Y values don’t match
Sorry if I’m wrong

X=25 and u would add 5x to both sides 6x=25+5x then u would multiply both sides by 0.25 making it 1.5x=6.25+1.25x

3. -4x - 6

-3(x + 2) - x → ( distribute bracket by - 3)

= - 3x - 6 -x → (collect like terms)

=( - 3x - x) - 6 = - 4x - 6
